WIHA Hex L-Key Set is made with ErgoStar, a mechanism that stores and conveniently organizes all L Keys. Turning one L-key in the holder makes all other keys turn to the side at the same angle, enabling you to remove the key you need quickly and comfortably. A clamping mechanism in the holder makes sure that the keys cannot fall out, regardless of whether the holder is open or closed. This set is made with the stainless steel MagicRing screw-holding spring, the L-keys hold all standard hex screws firmly in any position perfectly no matter what the screw is made of. This ensures that removing sunken screws or inserting and fastening a screw at an angle down to 25 Degrees is an extremely simple task. Each hex key consists of premium-quality tool steel and feature a satin finish for corrosion protection. The tips are fit with a chamfered end for smooth fastener engagement with CNC precision-machined tips for reduced cam-out. Wiha PocketStar Hex Key Sets are designed and engineered by Wiha Germany and manufactured by Wiha globally.
